CompTIA Linux+ (XK0-004) — Question 204

A systems administrator wants to disable the isofs module on the server.
Which of the following will allow the administrator to check if the isofs module is currently in use?

Answer options

• A. modprobe
• B. insmod
• C. rmmod
• D. lsmod

Correct answer: D

Explanation

The correct answer is D, as the 'lsmod' command lists all currently loaded modules, including whether 'isofs' is in use. Options A, B, and C serve different purposes: 'modprobe' loads modules, 'insmod' inserts a module, and 'rmmod' removes a module, none of which provide the status of currently loaded modules.
